Could be sport specific, or gender specific for that matter. What ThankYouforHelp describes sounds a lot like the unofficial visits my son went on, absent the comedy club at night. As far as official visits, I am mostly familiar with football recruiting, primarily at the D1 level, but for the most part the official visits my son and his teammates attended were full two day affairs, usually beginning with a get together dinner at a fancy restaurant the first night and then a day and a half of presentations by academic advisers, the strength and conditioning coach, dietitian and the like along with small group meetings with the position coach, etc., etc. in addition to the obligatory party with the host player. A lot of schools take the recruits to basketball games as well.
